Airfare is the purest example of point-of-sale pricing: the same seat costs different amounts depending where you ask from. Here's how to collect the whole price matrix.
Flight fares are point-of-sale priced — they vary by country, currency, and device — and meta-search sites (Google Flights, Skyscanner) load them through async JavaScript pricing calls. Collect them with a real browser on residential/mobile IPs in each point-of-sale country, set matching currency/locale, let results settle, and sample the same routes across markets to build the full matrix. Check terms and our legal overview first.
Airlines have priced by point-of-sale for decades — fare buckets and promotions differ by the country the ticket is sold in. Online that translates to your IP location shaping the quote. A single query from one country gives you one cell of a much larger price matrix; the value is in capturing all of them, so you can spot the cheapest origin market, monitor competitor fares, or feed a fare-alert product.
The technical work is browser automation against JS-heavy meta-search; the data-quality work is geography. That's why a country-diverse pool of trusted IPs is the real dependency — explored in depth in travel geo-pricing.
Yes. Airlines and aggregators segment fares by point-of-sale country, currency, and sometimes device, so the same flight can show different prices to a shopper in India versus Germany. To collect the fare a real customer in a market pays, you query from an IP in that country — point-of-sale is part of the price.
Both are JavaScript-heavy meta-search front-ends that fire live pricing requests after the page loads, then update results asynchronously. A static HTML fetch misses the real fares. You need a browser that runs the page (or a careful replay of the underlying pricing calls), and enough patience for results to settle before reading them.
Drive a real browser through residential or mobile IPs located in the point-of-sale countries you care about, set the matching currency/locale, and pace queries to look human. Sample the same routes from multiple countries to capture the full price matrix. Datacenter IPs both distort point-of-sale and get blocked quickly.
